lanelet2_core build fails because of missing includes

[odel4y]

Hello, I am trying to build the newest lanelet2 from git. I installed ROS Melodic from ros-melodic-ros-base in my Ubuntu 18.04 and then followed your installation instructions (including the extra dependencies). I also downloaded the catkin package into the workspace. When I try to build the workspace it fails with the following error:

I am not sure whether this is due to a misconfiguration on my part or actually a bug in lanelet2.

Hey, thanks for reporting that. Can you check if ros-melodic-rospack is installed on your system?

Its not a direct dependency of lanelet2 but a dependency of mrt_cmake_modules. I guess we should mention that in the install instructions...

[odel4y]

Thanks for the quick answer. Rospack is installed: ros-melodic-rospack is already the newest version (2.5.2-0bionic.20180906.220829).

[poggenhans]

Hm. Can test if rospack list-names works?

That is the command that fails with OSError: [Errno 2] No such file or directory during the build process.

[odel4y]

Yeah that works. I attached the output just in case:

Are you sure you didn't install that after the build failed? Otherwise I don't see how

import subprocess
subprocess.check_call(["rospack", "list-names"])

should fail during the build process when it works fine if you run it youself...

[odel4y]

I tried a few things including installing the full ros-melodic-desktop package and cleaning the workspace. It compiles successfully now. The catkin clean seems to have solved my issue. It now also builds with the ros-melodic-ros-base package. Sorry for the false alert. Still a note about rospack is probably useful in the installation instructions so one does not need the full ROS environment.

For those that want to work with a minimum of ROS dependencies: You need to follow the ROS install instructions but instead of installing a full ROS environment you only need the following packages:

ros-melodic-catkin
ros-melodic-rosbash
ros-melodic-rospack

After that just follow the provided installation guide for Lanelet2.
